HTTPS mixed content warning still showing even if base_url is set to https



We encounter mixed content warning on any browser we use. Checked base_url and it was set to HTTPS.

The error is specific to one image only

Your help will be much appreciated.

Thank you so much!


We are using
JIRA v5.2.11 running on nginx 1.6.2

Hi Rachel, 

Check your server.xml and ensure  "scheme", "proxyName" and "proxyPort" attributes are added, and match your environment. More on this can be found in the following article:

Hi David,


Thanks for your response. But after checking server.xml, all attributes are correct.

I wonder if it has something to do with our nginx configuration. Can help us figure out which one could be the cause of this?


Here is our /etc/nginx/conf.d/default.conf

proxy_cache_path /var/cache/nginx/jira levels=1:2 keys_zone=jira-cache:50m max_size=50m inactive=1440m;
server {
listen 8080;
server_name OURDOMAIN;
rewrite ^ https://$server_name:8443$request_uri? permanent;
server {
listen 8443 ssl;
server_name  OURDOMAIN;
ssl on;
ssl_certificate /etc/nginx/new_cert.pem;
ssl_certificate_key /etc/nginx/server_3year.key;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
ssl_session_cache shared:SSL:10m;
access_log /var/log/nginx/jira/jira.access.log main;
error_log /var/log/nginx/jira/jira.error.log error;
client_max_body_size 300M;




Hi Rachael, It looks like the location portion is missing from this configuration snippet. Do you have a location section that looks like what is described in the following article?

Hi David, Thank you very much for your help. But we also have location on our nginx config (default.conf) location / { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://OURDOMAIN:8100; set $do_not_cache 0; if ($request_uri ~* ^(/secure/admin|/plugins|/secure/projects|/projects|/admin)) { set $do_not_cache 1; } proxy_cache_bypass $do_not_cache; } Here is our server.xml <Connector port="8100" maxThreads="150" minSpareThreads="25" connectionTimeout="20000" enableLookups="false" maxHttpHeaderSize="8192" protocol="HTTP/1.1" useBodyEncodingForURI="true" redirectPort="8443" acceptCount="100" disableUploadTimeout="true" scheme="https" proxyName="OURDOMAIN" proxyPort="8443" secure="false" /> Did we miss something? Why only one image is causing mixed content warning?
